attribute NC_GLOBAL summary String Analyzed blended sea surface temperature over the global ocean using night only input data. An SST estimation scheme which combines multi-satellite retrieva\nls of sea surface temperature datasets available from polar orbiters, geostationary InfraRed (IR) and microwave sensors into a single global analysis. This global SST analysis provides\n a daily gap-free map of the foundation sea surface temperature at 0.05º spatial resolution. Note 2002-2016 is a reanalysis.  2017-present is near real-time processing.
